Create Color Composite (Data Management)

Summary

Creates a three-band raster dataset from a multiband raster dataset.

Usage

• When defining the band arithmetic algorithm, you can enter a single-line algebraic formula for each expression to create a multiband output. The supported operators are unary, plus (+), minus (-), times (*), and divide (/).

• When using a band ID in an expression, identify the band by prefixing the letter B or b to the band number.

Parameters

Dialog

Label	Explanation	Data Type
Input Raster	The input multiband raster data.	Raster Dataset; Raster Layer
Output Raster	The output three-band composite raster.	Raster Dataset
Method	Specifies the method that will be used to extract bands. Band names—The band name representing the wavelength interval on the electromagnetic spectrum (such as Red, Near Infrared, or Thermal Infrared) or the polarization (such as VH, VV, HH, or HV) will be used. This is the default. Band IDs— The band number (such as B1, B2, or B3) will be used.	String
Red Expression	The calculation that will be assigned to the first band. A band name, band ID, or an algebraic expression using the bands. The supported operators are unary: plus (+), minus (-), times (*), and divide (/).	String
Green Expression	The calculation that will be assigned to the second band. A band name, band ID, or an algebraic expression using the bands. The supported operators are unary: plus (+), minus (-), times (*), and divide (/).	String
Blue Expression	The calculation that will be assigned to the third band. A band name, band ID, or an algebraic expression using the bands. The supported operators are unary: plus (+), minus (-), times (*), and divide (/).	String
